Title: Glow discharge electron gun
IPC: H01J37/248
Filed: 1979-05-14
Abstract: A gun for use in glow discharge electron beam heating apparatus is constructed with an interchangeable module to facilitate removal and replacement of the gun in the heating apparatus. To achieve this the gun has one or more suspension means, such as 23, 24 (Fig. 1), forming inlet and outlet ducts for electrically insulating coolant, e.g. an oil, which suspension means support a cathode 18 within a shroud 22 constituting a support for an anode 14 having a central aperture 15 facing the cathode 18, the gap 20 between the anode and cathode being too small to allow ionisation and gas breakdown at the working voltage and working gas pressure but sufficiently wide to prevent high field breakdown. The suspension means, which are preferably flexible, in addition to supplying coolant to the cathode also form the electrical connection to the cathode of the gun by a conductor 27, and are terminated in a plug-type connector 28 for insertion in a co-operating socket 29 mounted in the wall 11 of the vacuum chamber. <IMAGE>

Title: Steerable aerials
IPC: H01Q3/08
Filed: 1979-05-29
Abstract: Common problems associated with steerable aerials are:   (i) the legs supporting the aerial mounting obstruct the full rotation of the antenna in azimuth; (ii) the legs also obstruct the antenna's full rotation in elevation at certain azimuth angles; and (iii) the antenna's elevation means is fully extended when the antenna is in the secure (horizontal) position, into which the antenna is put when gale force winds are ex- pected.   These problems are overcome in the aerial of the invention by:   (i) reducing the length and angle to the horizontal of the legs (6) so that they do not restrict the elevation angle of the antenna (9) at any azimuth angle; and (ii) mounting the antenna elevating screwjack (8), where it is clear of the supporting legs (6) and is in such a position that, from a vertical or intermediate, operating position, it pulls, rather than pushes, the antenna into the secure (horizontal) position, and is then in its least extended state.   <IMAGE>

Patent GB-2035491-A (GB)
Title: Over-run control system for hydraulically driven vehicles
IPC: B60K31/06
Filed: 1979-10-18
Abstract: The invention relates to a wheel-mounted excavator (E) driven by an hydraulic motor (1) and having a pneumatic braking system (B) which can be operated under control of a foot pedal (9) and also an over-run control system (14, 16, 17, 25) which comes into operation when the motor (1) is over-speeding by being driven by the vehicle, e.g. when the vehicle is travelling down an incline. Under these conditions the hydraulic pressure in the motor inlet line (2 or 3 depending on the direction of motor rotation) falls below that in the motor discharge line (3 or 2) and causes the hydraulic selector valve (25) to change over and apply this lower pressure to the cylinder (16) whereby its piston (17) moves under the pneumatic pressure applied to its other side to open the control valve (14) to apply pneumatic pressure to the brake system B. This pneumatic pressure is taken from the lines (22, 23) supplying compressed air to actuate the vehicle gearbox (G) so that the over-run system is only operative when the motor is geared to drive the vehicle wheels (W). <IMAGE>

Title: Optically readable digital information disc and manufacturing, recording and reading apparatus therefore
IPC: G11B7/24091
Filed: 1981-01-05
Abstract: When recording or reading digital information on or from a disc 5 on tracks at a fixed bit frequency fo, a clock signal is needed to synchronise the recording or reading process. To improve the reliability of the clock signal an optically detectable periodic track modulation d is provided on the blank record tracks whose period corresponds to a frequency (e.g. fo or 2 fo) at which the power spectrum (Figure 4) of the digitally coded information to be recorded or read exhibits a zero point. 
<??>Prior to recording the digital information, a laser beam (Figure 6a) is used to form a spiral servo track groove (4, Figure 1), the laser being modulated to record synchronisation areas (8) between information areas (9), the sync areas being recorded as depressions 13 representing (inter ala) address data, and the clock signal being recorded as a depth variation d in the groove and/or a groove width variation or as a lateral groove wobble (Figure 7). For track following purposes the groove may have a lateral wobble at a frequency which is low relative to the clock frequency, or equal or substantially equal to the clock frequency. The disc is then provided with a radiation sensitive recording layer 6, such as a reflective layer on a non-reflective substrate 5 or vice versa, and a laser beam (Figure 6b) is modulated with the digital information so as to form holes - 14 in layer 6. From the write beam reflected from the disc are extracted i the clock signal, used to synchronize modulation of the laser by the digital information, ii information from the sync areas (8), used to synchronize the laser modulation and also to cause recording at a desired portion of the track, and iii a tracking signal. An auxiliary beam (16b, Figure 13) may also be used to extract the clock signal during recording. These signals are also extracted during playback (Figures 6c, 8 to 12), the clock signal synchronising a read circuit (30) which extracts the information in the information and synchronisation areas (9), (8).

Title: Process for comminuting and activating limestone by reaction with CO2
IPC: C01F11/46
Filed: 1981-03-05
Abstract: The present invention relates to a non-mechanical method of converting coarsely ground limestone to a very fine powder. An aqueous slurry of ground calcium carbonate or limestone is contacted with carbon dioxide gas at high pressure to convert the solids in the slurry to an unstable form.
